Suppressing execution of monitoring measurement program pointed to by inserted branch after threshold number of coverage to reduce instruction testing overhead

摘要

In a method for testing a program, repeated measurement on branches that are frequently taken is prevented, thereby avoiding unnecessary overhead. An information processing device includes a coverage measurement control program for determining whether the number of times an instruction of a measurement target program has been executed due to execution of the measurement target program is equal to or larger than the maximum allowable number of measurements set for the instruction; and a coverage measurement program for incrementing a value in a field for the instruction by one to indicate the number of times the instruction has been executed, the coverage measurement program being called if the number of times the instruction has been executed is smaller than the maximum allowable number of measurements.
